Chorionic Villus Sampling (CVS) is a highly accurate prenatal diagnostic test, with 98–99% accuracy in detecting chromosomal abnormalities. Performed between weeks 10–13, it identifies genetic conditions like Down syndrome, but does not screen for neural tube defects. Results, while very reliable, are occasionally limited to the placenta.

Are CVS tests accurate?

CVS testing is very accurate and can be done early in pregnancy, between the 10th and 13th week. But it can only diagnose certain genetic diseases. A CVS test does not diagnose or screen for birth defects such as neural tube defects.

Can a CVS test be wrong?

CVS can find certain problems, but normal results don't guarantee that your baby will be healthy. In rare cases, the chorionic villus cells may have abnormal genetic material even though the baby's cells are normal. This is called a false-positive result, Opens dialog.

What is the success rate of the CVS test?

Our study showed that CVS provided conclusive results for 97.5%, 100%, and 86.5% of patients with high-risk NIPT results for trisomy 21, 18, and 13, respectively. The risk for a secondary amniocentesis is the highest for trisomy 13 (13.5%) and lower for trisomy 21 (2.5%) and trisomy 18 (0%).

Is CVS 100% accurate?

How reliable are the results? CVS is estimated to give a definitive result in 99 out of every 100 women having the test. But it cannot test for every condition and it's not always possible to get a conclusive result.

What is the 98% rule at CVS?

The CVS 98% rule is a popular couponing tip where shoppers aim to spend at least 98% of the required total for a "spend X,getcap X comma g e t𝑋,𝑔𝑒𝑡Y ExtraBucks" promotion (e.g., spend $20 get $10) to trigger the reward, often used when prices end in .99, but it's not an official policy and depends on individual store systems.

What is the best time of day to test?

The best time to take a test is often early in the day, like 8-11 AM, when cognitive function peaks after rest, leading to higher scores, especially for low-stakes tests, but personal alertness (your chronotype) matters significantly, so late morning (around 10 AM) or midday (11 AM - 2 PM) can work well for some, while others prefer afternoon slots, and short breaks before testing also boost performance. 

What is the CVS assessment test?

The situational judgment test is a multiple-choice assessment where you are presented with a range of scenarios in which you must choose the most and least effective solution. This helps CVS assess the type of decision-maker you are and if you can make logical, fair and effective choices during challenging situations.
